Face mask use during judgment surgery

British Journal of Ophthalmology, September 2002

Postoperative bacterial endophthalmitis after cataract surgery although rare (ie, five disclosed of 10,000 patients), is a complication of major matter (1) It may result in decreased vision or permanent vision los and, in an instances, a patient may require enucleation to eradicate a blind and painful observation This study evaluated whether surgeons' use of face masks during cataract surgery reduc the contortion of potentially infective organisms falling forward the surgical field.

brace hundred twenty-one consecutive patients undergoing phacoemulsification cataract surgery were assigned randomly to dispose A (ie, the surgeon wore a face mask from one extremity to the other of the procedure) or group B (ie, the surgeon did not wear a face mask). family agar settle plates were placed adjacent to patients' heads in the OR. At the period of the procedure, plates were incubated, and they were read after 48 hours. Colony-forming bacteria were identified and counted

Findings. Significantly fewer organisms were set up on the settle plates from patients in assign places to A (P = .0006). Eighty-four percent of the bacteria grown were Staphylococcus epidermidis, Bacillus, or diphtheroid, which are potential intraocular pathogens. None of the patients expanded bacterial endophthalmitis.

Clinical implications. The clinical significance of bacterial organisms falling upon the surgical field was not established; however, this meditation acknowledged that one purpose of wearing a face mask is to obstruct bacteria from falling on the surgical field. It hints that wearing a face mask during all surgical transactions may be important in reducing the potential of patients developing postoperative bacterial infections. Perioperative encourages can use this information to encourage compliance to existing policies in their institutions regarding the use of face masks during surgery

gentle back pain

Journal of Orthopaedic & Sports Physical Therapy, September 2002

Nationally, it is estimated that 80% of adults experience cheap back pain, and hospitals lead all industries in wasted work days caused by cheap back pain. (2) This consideration investigated the association among mechanical factors and the proceeding of low back pain. Six hundr participants ages 20 to 65 were recruited randomly from five hospitals and categorized into four disposes (ie, asymptomatic men, asymptomatic women men with subdued back pain, women with cheap back pain). Participants further were divided into age clusters (ie, ages 20 to 35 ages 36 to 50 ages 51 to 65)

The relative association of 17 characteristics of depressed back pain was assessed. Characteristics included size of lumbar lordosis; angle of pelvic tilt; amplification of abdominal muscles, low back extensor muscles, hip flexor muscles, hamstring muscles, hip abductor muscles, gastrocnemius muscles, and the iliotibial band; leg amplification discrepancy; endurance of erector spinae muscles; bottom arch height; and strength of hip flexor, hip extensor, hip abductor, hip adductor, and abdominal muscles. Backward logistic regression analysis was used to determine the station of association between selected variables and depressed back pain.

Findings. Endurance of back extensor muscles had the highest association with cheap back pain. The length of hamstring and back extensor muscles, iliotibial band tightness, and the potency of hip flexor, hip extensor, hip abductor, hip adductor, and abdominal muscles all were establish to be significantly associated with grave back pain.

Clinical implications. Perioperative nursing managers should understand that grave back pain may be associated with muscle weakness. To decrease the incidence of depressed back pain in personnel, they should consider implementing periodic testing of back extensor muscle endurance as a screening tool.

Reducing surgical site infection

Clinical Infectious Diseases, Aug 15 2002

Preoperative nasal carriage of Staphylococcus aureus has been identified as a risk factor for unfolding of surgical site infection (SSI). (3) The meaning of this randomized, double-blind subject of attention was to determine whether mupirocin nasal ointment used preoperatively was effective in preventing the disclosure of SSI. Patients scheduled for elective orthopedic surgery involving prosthetic implants were assigned randomly to receive mupirocin or a placebo nasal ointment twice daily until the day of surgery The day before surgery hair was remov with a depilatory cream, if necessary. Nasal improvements were obtained preoperatively and postoperatively. The progressive growth of SSI was determined up to single month after surgery.

Findings. Mupirocin was significantly more effective in eradicating nasal carriage of Staphylococcus aureus than the placebo (835% versus 278% P < 05) The SSI rate in as well-as; not only-but also; not only-but; not alone-but groups was comparable (3.8% in the mupirocin clump versus 4.6% in the placebo group) Endogenous Staphylococcus aureus infection, although not statistically significant, was five times les likely to disentangle in patients in the mupirocin dispose (relative risk 0.19; 95% confidence interval [CI], 002-162)
